Armazenamento refrigerado da uva de mesa 'Romana' (A1105) cultivada sob cobertura plástica

摘要

The grapevine is one of the most cultivated fruit crop and nowadays the preference for seedless grapes is gradualy increasing in the Brazilian internal market. The table grape cultivar 'Romana' (A1105) has been showing potential as a new option for the growers from Jundiaí - SP, Brazil, as a seedless grape. However the bunch quality has been affected by rain at the harvest allowing the incidence of cracking and bunch rot. Aiming to solve this problem a field trial was carried out with grapes cultivated under plastic cover and Geneva Double Curtain training system. After harvest, eight samples of six bunches each were taken and stored at 3oC and evaluated for quality during a period of 36 days. After three weeks of storage, the weight loss was higher than 6%, showing bunch fade and the rot bunch increased significantly. It was concluded that maximum shelf life for the 'Romana' (A1105) table grape cultivar was 21 days.
